Each time a slab is deactivated, the page and freelist pointer should be
reset.
This patch just merges these two options into deactivate_slab().

OK, I see your point, thanks. Post the two options here for an analysis:
Option1 (what we have now):
struct virtio_balloon_page_chunk {
__le64 chunk_num;
struct virtio_balloon_page_chunk_entry entry[];
};
Option2:
struct virtio_balloon_page_chunk {
__le64 chunk_num;
struct scatterlist entry[];
};
I don't have an issue to change it to Option2, but I would prefer Option1,
because I think there is no be obvious difference between the two options,
while Option1 appears to have little advantages here:
1) "struct virtio_balloon_page_chunk_entry" has smaller size than
"struct scatterlist", so the same size of allocated page chunk buffer
can hold more entry[] using Option1;
2) INDIRECT needs on demand kmalloc();
3) no 4G size limit;
What do you think?
Best,
Wei

The negotiation of the existing feature flag, VIRTIO_BALLOON_F_STATS_VQ
only indicates the support of the old statq implementation. To move the statq
implementation under cmdq, I think we would need a new feature flag for the
new statq implementation:
#define VIRTIO_BALLOON_F_CMDQ_STATS 5
What do you think?

Wei

OK, thanks. Would this be your suggestion:
struct virtio_balloon_page_struct {
unsigned int page_bmap_num;
unsigned long *page_bmap[VIRTIO_BALLOON_PAGE_BMAP_MAX_NUM];
}

mm/usercopy: Drop extra is_vmalloc_or_module() check
Previously virt_addr_valid() was insufficient to validate if virt_to_page()
could be called on an address on arm64. This has since been fixed up so
there is no need for the extra check. Drop it.

* [PATCH] mm/khugepaged: Add missed tracepoint for collapse_huge_page_swapin
From: SeongJae Park @ 2017-05-07 10:18 UTC (permalink / raw)
To: akpm, kirill.shutemov; +Cc: hannes, linux-mm, linux-kernel, SeongJae Park
One return case of `__collapse_huge_page_swapin()` does not invoke
tracepoint while every other return case does. This commit adds a
tracepoint invocation for the case.

* [RFC 00/10] x86 TLB flush cleanups, moving toward PCID support
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)
To: X86 ML
Cc: linux-kernel@vger.kernel.org, Borislav Petkov, Linus Torvalds,
Andrew Morton, Mel Gorman, linux-mm@kvack.org, Andy Lutomirski
As I've been working on polishing my PCID code, a major problem I've
encountered is that there are too many x86 TLB flushing code paths and
that they have too many inconsequential differences. The result was
that earlier versions of the PCID code were a colossal mess and very
difficult to understand.
This series goes a long way toward cleaning up the mess. With all the
patches applied, there is a single function that contains the meat of
the code to flush the TLB on a given CPU, and all the tlb flushing
APIs call it for both local and remote CPUs.
This series should only adversely affect the kernel in a couple of
minor ways:
- It makes smp_mb() unconditional when flushing TLBs. We used to
use the TLB flush itself to mostly avoid smp_mb() on the initiating
CPU.
- On UP kernels, we lose the dubious optimization of inlining nerfed
variants of all the TLB flush APIs. This bloats the kernel a tiny
bit, although it should increase performance, since the SMP
versions were better.
Patch 10 in here is a little bit off topic. It's a cleanup that's
also needed before PCID can go in, but it's not directly about
TLB flushing.
Thoughts?
This applies to tip:x86/mm. You can see it fully applied here:
https://git.kernel.org/pub/scm/linux/kernel/git/luto/linux.git/commit/?h=x86/tlbflush_cleanup&id=59ea83a0a78025439e3d15e09b693846fa1f4770
Andy Lutomirski (10):
x86/mm: Reimplement flush_tlb_page() using flush_tlb_mm_range()
x86/mm: Reduce indentation in flush_tlb_func()
x86/mm: Make the batched unmap TLB flush API more generic
x86/mm: Pass flush_tlb_info to flush_tlb_others() etc
x86/mm: Change the leave_mm() condition for local TLB flushes
x86/mm: Refactor flush_tlb_mm_range() to merge local and remote cases
x86/mm: Use new merged flush logic in arch_tlbbatch_flush()
x86/mm: Remove the UP tlbflush code; always use the formerly SMP code
x86/mm: Rework lazy TLB to track the actual loaded mm
x86,kvm: Teach KVM's VMX code that CR3 isn't a constant

* [RFC 01/10] x86/mm: Reimplement flush_tlb_page() using flush_tlb_mm_range()
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)
To: X86 ML
Cc: linux-kernel@vger.kernel.org, Borislav Petkov, Linus Torvalds,

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
flush_tlb_page() was very similar to flush_tlb_mm_range() except that
it had a couple of issues:
- It was missing an smp_mb() in the case where
current->active_mm != mm. (This is a longstanding bug reported by
Nadav Amit.)
- It was missing tracepoints and vm counter updates.
The only reason that I can see for keeping it at as a separate
function is that it could avoid a few branches that
flush_tlb_mm_range() needs to decide to flush just one page. This
hardly seems worthwhile. If we decide we want to get rid of those
branches again, a better way would be to introduce an
__flush_tlb_mm_range() helper and make both flush_tlb_page() and
flush_tlb_mm_range() use it.

* [RFC 02/10] x86/mm: Reduce indentation in flush_tlb_func()

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
The leave_mm() case can just exit the function early so we don't
need to indent the entire remainder of the function.

* [RFC 03/10] x86/mm: Make the batched unmap TLB flush API more generic
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)
To: X86 ML

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
try_to_unmap_flush() used to open-code a rather x86-centric flush
sequence: local_flush_tlb() + flush_tlb_others(). Rearrange the
code so that the arch (only x86 for now) provides
arch_tlbbatch_add_mm() and arch_tlbbatch_flush() and the core code
calls those functions instead.
I'll want this for x86 because, to enable address space ids, I can't
support the flush_tlb_others() mode used by exising
try_to_unmap_flush() implementation with good performance. I can
support the new API fairly easily, though.
I imagine that other architectures may be in a similar position.
Architectures with strong remote flush primitives (arm64?) may have
even worse performance problems with flush_tlb_others() the way that
try_to_unmap_flush() uses it.

* [RFC 04/10] x86/mm: Pass flush_tlb_info to flush_tlb_others() etc
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
Rather than passing all the contents of flush_tlb_info to
flush_tlb_others(), pass a pointer to the structure directly. For
consistency, this also removes the unnecessary cpu parameter from
uv_flush_tlb_others() to make its signature match the other
*flush_tlb_others() functions.
This serves two purposes:
- It will dramatically simplify future patches that change struct
flush_tlb_info, which I'm planning to do.
- struct flush_tlb_info is an adequate description of what to do
for a local flush, too, so by reusing it we can remove duplicated
code between local and remove flushes in a future patch.

* [RFC 05/10] x86/mm: Change the leave_mm() condition for local TLB flushes

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
On a remote TLB flush, we leave_mm() if we're TLBSTATE_LAZY. For a
local flush_tlb_mm_range(), we leave_mm() if !current->mm. These
are approximately the same condition -- the scheduler sets lazy TLB
mode when switching to a thread with no mm.
I'm about to merge the local and remote flush code, but for ease of
verifying and bisecting the patch, I want the local and remote flush
behavior to match first. This patch changes the local code to match
the remote code.

* [RFC 06/10] x86/mm: Refactor flush_tlb_mm_range() to merge local and remote cases

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
The local flush path is very similar to the remote flush path.
Merge them.
This is intended to make no difference to behavior whatsoever. It
removes some code and will make future changes to the flushing
mechanics simpler.
This patch does remove one small optimization: flush_tlb_mm_range()
now has an unconditional smp_mb() instead of using MOV to CR3 or
INVLPG as a full barrier when applicable. I think this is okay for
a few reasons. First, smp_mb() is quite cheap compared to the cost
of a TLB flush. Second, this rearrangement makes a bigger
optimization available: with some work on the SMP function call
code, we could do the local and remote flushes in parallel. Third,
I'm planning a rework of the TLB flush algorithm that will require
an atomic operation at the beginning of each flush, and that
operation will replace the smp_mb().

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
Now there's only one copy of the local tlb flush logic for
non-kernel pages on SMP kernels.
The only functional change is that arch_tlbbatch_flush() will now
leave_mm() on the local CPU if that CPU is in the batch and is in
TLBSTATE_LAZY mode.

* [RFC 08/10] x86/mm: Remove the UP tlbflush code; always use the formerly SMP code
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)

Arjan van de Ven
In-Reply-To: <cover.1494160201.git.luto@kernel.org>
The UP tlbflush generates somewhat nicer code than the SMP version.
Aside from that, it's fallen quite a bit behind the SMP code:
- flush_tlb_mm_range() didn't flush individual pages if the range
was small.
- The lazy TLB code was much weaker. This usually wouldn't matter,
but, if a kernel thread flushed its lazy "active_mm" more than
once (due to reclaim or similar), it wouldn't be unlazied and
would instead pointlessly flush repeatedly.
- Tracepoints were missing.
Aside from that, simply having the UP code around was a maintanence
burden, since it means that any change to the TLB flush code had to
make sure not to break it.
Simplify everything by deleting the UP code.

* [RFC 09/10] x86/mm: Rework lazy TLB to track the actual loaded mm
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)
To: X86 ML

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
Lazy TLB state is current managed in a rather baroque manner.
AFAICT, there are three possible states:
- Non-lazy. This means that we're running a user thread or a
kernel thread that has called use_mm(). current->mm ==
current->active_mm == cpu_tlbstate.active_mm and
cpu_tlbstate.state == TLBSTATE_OK.
- Lazy with user mm. We're running a kernel thread without an mm
and we're borrowing an mm_struct. We have current->mm == NULL,
current->active_mm == cpu_tlbstate.active_mm, cpu_tlbstate.state
!= TLBSTATE_OK (i.e. TLBSTATE_LAZY or 0). The current cpu is set
in mm_cpumask(current->active_mm). CR3 points to
current->active_mm->pgd. The TLB is up to date.
- Lazy with init_mm. This happens when we call leave_mm(). We
have current->mm == NULL, current->active_mm ==
cpu_tlbstate.active_mm, but that mm is only relelvant insofar as
the scheduler is tracking it for refcounting. cpu_tlbstate.state
!= TLBSTATE_OK. The current cpu is clear in
mm_cpumask(current->active_mm). CR3 points to swapper_pg_dir,
i.e. init_mm->pgd.
This patch simplifies the situation. Other than perf, x86 stops
caring about current->active_mm at all. We have
cpu_tlbstate.loaded_mm pointing to the mm that CR3 references. The
TLB is always up to date for that mm. leave_mm() just switches us
to init_mm. There are no longer any special cases for mm_cpumask,
and switch_mm() switches mms without worrying about laziness.
After this patch, cpu_tlbstate.state serves only to tell the TLB
flush code whether it may switch to init_mm instead of doing a
normal flush.
This makes fairly extensive changes to xen_exit_mmap(), which used
to look a bit like black magic.
Perf is unchanged. With or without this change, perf may behave a bit
erratically if it tries to read user memory in kernel thread context.
We should build on this patch to teach perf to never look at user
memory when cpu_tlbstate.loaded_mm != current->mm.

* [RFC 10/10] x86,kvm: Teach KVM's VMX code that CR3 isn't a constant
From: Andy Lutomirski @ 2017-05-07 12:38 UTC (permalink / raw)
To: X86 ML

In-Reply-To: <cover.1494160201.git.luto@kernel.org>
When PCID is enabled, CR3's PCID bits can change during context
switches, so KVM won't be able to treat CR3 as a per-mm constant any
more.
I structured this like the existing CR4 handling. Under ordinary
circumstances (PCID disabled or if the current PCID and the value
that's already in the VMCS match), then we won't do an extra VMCS
write, and we'll never do an extra direct CR3 read. The overhead
should be minimal.
I disallowed using the new helper in non-atomic context because
PCID support will cause CR3 to stop being constant in non-atomic
process context.
(Frankly, it also scares me a bit that KVM ever treated CR3 as
constant, but it looks like it was okay before.)

Looks really nifty! The diffstat alone appears to be worth it:

This appears to be from CONFIG_DEBUG_VIRTUAL on __phys_addr, used by
hardened usercopy, probably during virt_addr_valid(). I'll take a
closer look on Monday...

Looks fine to me. I'm always a bit nervous about TLB changes like this
just because any potential bugs tend to be really really hard to see
and catch, but I don't see anything wrong in the series.

Please integrate scripts/checkpatch.pl in your patch creation workflow.
Some of the warnings/errors *actually* make sense.
I know, the other function prototypes have a space too but that's not
our coding style. Looks like this trickled in from ia64, from looking at
arch/ia64/kernel/efi.c.

Right, and the refcount taken for memory_failure is not freed after
memory_failure() returns. unpoison_memory() does free the refcount.

memory_failure() can be called for any types of page (including slab or
any kernel/driver pages), and the reported problem seems happen only on
in-use user pages, so uncharging in delete_from_lru_cache() as done below
looks better to me.

Any further comments? I think introducing a general madvise option or a
mmap flag applicable to all filesystems, may not be required. The
'noautofill' behavior would be specifically useful in hugetlbfs filesystem.
So, if it is specific to hugetlbfs, will the mount option be ok?
Otherwise adding a madvise / mmap option specific to hugetlbfs, be
preferred?

* Q: si_code for SIGBUS caused by mmap() write error
From: Stoermeldung Infrastruktur-Ukr @ 2017-05-08 9:27 UTC (permalink / raw)
To: linux-mm@kvack.org; +Cc: Ulrich Windl, linux-kernel
In-Reply-To: <59103A09020000D3000127FA@gwsmtp1.uni-regensburg.de>
[-- Attachment #1.1: Type: text/plain, Size: 1024 bytes --]
Hi!
I observed this for 3.0.101-97 kernel (SLES11 SP4, x86_64): When a mmap()ed file has a write error (e.g. bad sector), the program is terminated with SIGBUS. Trying to handle the situation, I noticed that the error code in siginfo is 2 (BUS_ADRERR, nonexistent physical address). My expectation was that the error would be 3 (BUS_OBJERR, object-specific hardware error).
For debugging I created this dummy device with a bad block:
DEV=bad_disk
dmsetup create "$DEV" <<EOF
0 8 zero
8 1 error
9 255 zero
EOF
The kernel error logged is " kernel: [2932614.419355] Buffer I/O error on device dm-8, logical block 1"
Is my expectation on the si_code wrong, or is the implementation wrong?
At a quick glance at do_sigbus() of /usr/src/linux/arch/x86/mm/fault.c I see that only codes BUS_ADRERR (default) and BUS_MCEERR_AR are used. However I don't know whether I looked at the correct source.
(The code in 4.4.62 still looks similar)
Regards,
Ulrich Windl
P.S: Keep me on CC: in your replies, please!
